Strictly speaking, it is not always necessary to place a separator between two tokens; for example, the code fragment Size:=20;Price:=10; is perfectly legal. Convention and readability, however, dictate that we write this as Size := 20; Price := 10; Tokens are categorized as special symbols, identifiers, reserved words, directives, numerals, labels, and character strings. A separator can be part of a token only if the token is a character string.
